PIPE-J OIN T.

Application led February 28, 1919.

' To all whom it'mw concern:

Pipe-Joints, of which the following is av specification.

This* invention relates to pipe-joints and joint-mold therefor, and hasfor one of its objects to provide, in a manner as herelnafter referredto, a pipe joint wherebyhthe molten metal cast around the pipe sectionswill be prevented from burning through the ends of the overlapping pipesections under such conditions overcoming leakage when the joint isformed. u

A further object of the invention, 1s to provide, in a manner ashereinafter referred to, a joint mold which may be qulckly and nicelyfitted around the pipe sections to be joined, and which will ena lemolten metal to be cast at the joint in a uniform manner giving thejoint a neat appearance when comp eted.

A further object of the invention is to provide in a manner ashereinafter set forth, means for joining pipes of the same or differentdiameters, and refers more especially to such joints known as wipedjolnts, whereby the ends of pipes of different metals may be joined,such as lead and brass,

and when joined providing a neat or unii form joint and overcomingleakage due to the burning through of the pipe sections, at

their ends, caused by the molten metal when cast to form the joint.

With the foregoing and other objects inl view the invention resides inthe novel combination, construction and arrangement of parts ashereinafter referred to and illustrated in the accompanying drawings,wherein is shown an embodiment of the invention, but it is to beunderstood lthat changes, variations and modifications canbe resorted towhich come within the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote correspondingparts throughout the several views Figure 1, is a longitudinal sectionalview of the joint and joint mold.

Fig. 2, is a section on line II-II Fig. 1.

Fig. 3, is a view similar to Fig. l of a modified form of joint.

ferring to the drawings in detail 1 and Specification of Letters Patent.

in case the metal 4 bodies 9, has spaced lugs 16, between which extendsthe `lug 15.

' tions of Patented Jan. 18, 1921. serial No. 279,820.

2 denote a pair of pipe sections, the former overlapping the latter, andarranged therein, at the joint ends of the pipe sections, 1, 2, 1sasleeve 3, of metallic material different from that of which the pipesections are toi-med, and also different from the character'of themolten metal 4, which `is cast Y around the pipe sections 1, 2 to closethe joint. Preferably when the pipe sections 1 2 are formed of lead, thesleeve 3, is of brass. The sleeve 3 is welded to the pipe sections 1, bythe heat from the molten metal 4; which is cast around said pipesections, and burns through either of l, 2 the sleeve 3 being weldedagainst the pipe sections will act as a means to seal the opening formedin the pipe sections by the metal 4.

he pipe sections 1, 2 may be tinned, if desired, prior to the casting ofthe metal 4 around them. The sleeve 3 is of a length equal to the lengthof the cast around the pipe sections.

In the modified form shown in Fig. 3, the sleeve is indicated at 5, andis mounted on the periphery of the pipe sections `6, 7, and which' isslightly less in length than the length of the cast 8. The sleeve 5 willprevent the burning through of the pipe sections and is welded theretoby the heat from the pipe sections Vthe molten metal which is employedto form the cast 8.

The joint mold, which is employed in forming either form of joint, isformed of two sections each comprising a hollow semielliptical bodyportion 9, terminating at each end in a semi-cylindrical extension,which are indicated at 10, 11. The upper portion of the body 9, at theedge thereof is grooved as at 12, 13, the former being larger than thelatter. The extension 10 is formed with a handle member 14.

One of the bodies 9, has a lateral lug 15, which is apertured, and theother of the a pair of apertured lateral The lugs 15 and 16 areconnected by a pin 17, whereby the two secthe joint mold are hingedtogether.

The extensions 10, 11 when the mold is mounted on the pipe sections formsectional collars, which in connection with the clamping screws 18,maintain the mold in position on the pipe sections.

When the sections of the mold are mounted on the pipe sections andclamped in positogether tion, the groove 12 of one section registersWith the groove 12 of the other section :md forms :i pouring opening forthe molten metal which is to be cast around the pipe sections.

When the sections of the mold are clamped on the pipe sections thegroove 13 of one mold section registers with the groove 13 of the othermold section and :i vent open in?` is provided for air, ges or vapor.

uitable means may be employed for connecting the handle members 14together t0 clamp the mold sections in position on the pipe sections.

What I claim is 1. A pipe-joint comprising the combination with the endsof a pair of pipe sections,

of a body of metal cast around seid ends, and :L metallic sleeveengaging said ends und welded therewith by the heut from said mst metalbody, the sleeve being of :i metall dif ferent from that of which thepipe sections` und cast metal body is formed.

2. A pipe joint comprising the combination with the overlripping` endsof :1 pair olf pipe Sections, of :L metallic sleeve arranged Within saidsections :it Suid overlapping ends, and e body of metal cast u round.said overlapping ends to close the joint, said body of :i dilerent metal'lrom that el? which the sleeve is formed und seid sleeve welded to saidsections by the host from said body,

In testimony whereof I :illix my signature.
